Method and apparatus for electronically generating an outline indicating the size of an energy zone imaged onto the IR detector of a radiometer
First Claim
1. A system for indicating the location of an energy zone on an object surface, with the energy zone being an area on the object surface that is imaged onto an IR detector by the IR optical system included in a non-contact IR thermal measurement device, said system comprising:
- a light source for projecting a light beam spot on the object surface;
a video sub-system for displaying a displayed image of at least a part of the object surface and the light beam spot;
a shape size determining sub-system, coupled to the video sub-system, that utilizes the video sub-system and location of the light beam spot to determine the size of an energy zone indicating shape to be displayed; and
an optical overlay sub-system, coupled to the shape size determining sub-system and video sub-system, for displaying the shape over a displayed image of the object surface and with an overlayed shape indicating the part of the displayed image included in the energy zone.

Abstract
A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. In one embodiment, a shape is displayed between the locations of two imaged skewed laser dots to indicate the extent of the energy zone without requiring a range determination.

4. A system for indicating the location of an energy zone on an object surface, with the energy zone being an area on the object surface that is imaged onto an IR detector by the IR optical system included in a non-contact IR thermal measurement device, said system comprising:
-
a video sub-system for displaying a displayed image of at least a part of the object surface; at least two laser diodes for emitting skewed laser beams to form at least two laser spots on an object to be imaged that indicate the periphery of the energy zone which varies at different locations; a laser spot location indicator that indicates the locations of the laser spots in the displayed image; and an optical overlay sub-system, coupled to the video sub-system and the laser spot location indicator, for overlaying a shape outline, having a dimension determined by locations of the laser spots, over a displayed image of the object surface and with the shape outline substantially centered between the imaged skewed laser spots and having a diameter substantially equal to the displacement between the laser spots, with the shape outline indicating the part of a displayed image included in the energy zone. - View Dependent Claims (5, 6)
